I took Miaoqing's patch out and applied v4 1-11 instead, on v7.4-rc1 plus three ath12k commits from ath.git (c752394249f8 and 02121aa4a012 from ath-next, 1e678e37ff13 from ath-current) and out-of-tree Glymur platform/board patches; the tree also carries Miaoqing's dp_peer reconnect fix (8b6b871332b5). All 11 applied as posted. On the tri-band MLO SSID that failed with reason 15 (SAE, PMF required, 2.4+5+6 GHz): - 12 of 12 connect/disconnect cycles completed the 4-way handshake and came up as MLO with three links (2.4 and 6 GHz active), ping OK each time; no reason 15 in 23 handshakes over the session - 5 of 5 rejoins after s2idle resume - non-MLO WPA2 on 5 GHz still fine This firmware sends the PEER_EXTENDED event (two per association), so the host allocation path in 8/11 was not exercised. I'll send a Tested-by on the cover letter. Tested-on: QCC2072 hw1.0 PCI WLAN.COL.1.0.c2-00277-QCACOLSWPL_V1_TO_SILICONZ-1 AI coding assistants helped run these tests and draft this reply; the results are from the hardware runs. Thanks, Burke
